Integrate liquidation redeem flow into the UI for Pendulum and Amplitude

[annatekl]

Context

The ticket is for enhancing the current Spacewalk portal UI to include the functionality for users to redeem their assets for KSM/DOT/vDOT or any other assets used in the future as collateral on Pendulum and Amplitude in the event of a vault liquidation. This involves adding logic to check for the availability of a LiquidationVault and providing the necessary options for users to either bridge wrapped tokens back to Stellar or exchange them for collateral asset on Amplitude/Pendulum.
